TY - Data T1 - Heihe integrated remote sensing joint test: L & K band airborne microwave radiometer ground synchronous observation data set in biandukou encrypted observation area (July 4, 2008) A1 - Zhao Shaojie A1 - Ran youhua A1 - Wang Yang DO - 10.12072/ncdc.NIEER.db1898.2022 PY - 2022 DA - 2022-03-15 PB - National Cryosphere Desert Data Center AB - On July 4, 2008, the ground synchronous observation for airborne microwave radiometer (LK band) was carried out in the Bian Du Kou encrypted observation area. The measurement contents are mainly soil temperature and soil moisture. 1. Soil temperature and soil moisture: the soil temperature is measured by hand-held infrared thermometer from flat mouth sample belt 1 to flat mouth sample belt 8; Soil moisture is measured by ml2x soil moisture rapid meter. There are 1-8 transects in biandukou, with 9 points each, the interval between points is 200m, the length is 1.6km, and the distance between transects is 1km 2. Quadrat survey: 1-5 sampling specification: 50cm × 50cm survey contents: GPS number of sample point, vegetation type, vegetation height, actual number, self sealing bag number, wet weight + garbage bag (g), dry weight + envelope bag (g), envelope bag weight and photo number. The data is stored in Excel format. DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/c5fe9526-96ee-4e03-957b-42d79e9654d7 ER -
